ELAM A. OLIVER, OF BELLEVILLE, VISCONSIN.

SPECIFICATIQN forming part of Letters Application filed March 30, 1887.

To all whom t may concern:

Be it known that I, ELAM A. OLIVER, a citizen of the United States, resident at Belleville, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Compound Metal-Vorking Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

VFigure l of the drawings isa representation of a front elevation. Fig. 2 is a side elevation. Fig. 3 is a detail View, partly in section. Fig. 4 is a detail view showing a modication, and Figs. 5 and G are detail views.

The invention relates to improvements in compound n'ietal-'working machines; and it consists, mainly, inthe construction and arrangement of the detachable metalholding jaws or heads and the combination of the same with certain other parts,hereiuafter described.

It consists, further, in Vcertain details of construction and arrangement hereinafter described, illustrated in the drawings, and pointed out in the claims hereto appended.

Referring to the drawings by letter, A designates the frame of the machine, composed 'of the base-plate a. and standard a', rising therefrom.

a2 a2 are similar arms extending out horizontally on each side from the standard, and which, bending` downward, have their feet bolted to the base-plate a.

B is the footlever, provided with a suitable pedal, I), having its stem bifurcated,` with the arms of the bifurcation passing on opposite sides of the Astandard a suitable distance below the arms a2, and pivoted upon the horizontal bar b, secured centrally in an opening through the standard. t

C C are springs, the coiled portions c of which surround the arms of the bar b on opposite sides of the standard, their upper ends bearing against the horizontal parts of the arms a, while their lower ends pass through openings in the corresponding arms of apin, c', secured centrally in an opening in the lever B, near the lower ends of the arms of its bifureation.

Patent No. 367,658, dated August 2, 1887.

Serial No. 233,047.` (No model.) a

D is an upwardlystanding bar similar to the standard a', both standard and bar having their upper ends provided with similar recu angular shoulders, d d, for the attachment of the metal-workingjaws, hereinafter described. The bar D is provided near its lower end with a longitudinal slot, d', for the passage of the pin c', and is pivoted, at a suitable distance below its upper end, between the horizontal arms E, secured upon the standard on oppo site sides thereof, the corresponding ends of `the arms being ilanged to iit upon the upper and lower edges of a rectangular bracket that fit-s around the standard, and has arms extending on each side of the bar D. rlhe pivotal bolt d of the bar passes through openings in the arms E and in the arms of the bracket and engages with 'a nut to keep the parts tightlyin place. The end parts, e, of the arms E curve outward and upward beyond the piv 'otal bolt, and are rabbeted on the inner side of their outer edges for the insertionof the edges of the die-pla`te Forthe plate against which a sheet of metalis punched, the said plate F being provided with the openingf for the passageof the punching-die.

G is the pu aching-die, secured to the inner surface near the top ofthe outwardly-bent arm g of the block y, which is grooved in its inner edge to titr upon the outer edge of the bar D and secured to said bar by the rectangular frame or yoke g, bent around the inneredge thereof, and lwith its threaded ends passing through suitable openings in the enlarged central portion of the block and engaging nuts on the outer side thereof.

H is a spring, the lower end of which is engaged between the said nuts and block, the ends of the yoke g passing through suitable openings in the said end. The spring H extends thence upward and bends over the upper end of the arm' g of the block, and then 95 Vextends downward on the inner side of the same, the end of the downwardly bent part being provided with a longitudinal notch, lz, the arms of which pass on each side of the punchingdie. Vhen thepedal 4is pressed down by the foot, the pin c moves upward in the slot d, moving the lower part of the bar D outward and its part above the pivotal bolt d2 inward, so that the punehingdie G is forced through the sheet of metal placed between it and the die-plate F and through the opening f in the latter.

arms ofthe spring II on each side of the notch lt hold the met-al plate inward and allow the punching-die to be withdrawn out'of the hole made therein.

I I aresimilar metal-holding jaws, provided with rsockets i i, that fit upon the upper ends, respectively, of the standard and of the bar D down to the. shoulder d thereon, and with the laterally-extended head portions z" fi, which may be scored to hold bars or plates of metal in any direction, but are preferably provided Y with corresponding semicireular notches, iff,

on their meeting faces, which notches are vertical and of varying sizes to hold metal bars of different diameters.

J is a bar or staff rectangular in cross-sec tion, and with its lower end fitting into either of the socketsjj, made at suitable points in the base-plate c* on each side of the standard a. The said staffis provided on its inner side with the transverse adj'usting-notchesjj at equal distances apart and seinicireular in cross-section.

L is an adjusting-block having a vertical opening, Z, which fits upon the staffJ,and has a transverse rib, Z', that is adapted to enter any one of the said notches, being semicircir lar in cross-section to fit therein. The upper portion of the block L is extended inwardly toward the standard,and has its uppersurface, M, horizontal when the block is adjusted in proper position. m is a key of suitable size to be passed between the staff J and the outer part of the opening Z, so as to lock the block L in place with its rib Z in any desired one of the adj listing-notches j. The said staff and block are intended-to gage the length of a bolt. The block also supports the lower end of the bolt, while its upper partis grasped between the proper vertical notches, i2, of the jaws I, and is shaped into a head by ahammcr, which may be either in the hands of the operator, who forces the jaws together upon the stem of the bolt by pressing his foot on the treadle, or may be actuated by suitablemech` anism. rlhe staff J is prevented from entering the socket too far or being unsteady therein by the circumferential collar j.

The machine as described is a compact, reliable, durable, and effective compound metal'- working machine, and is not liable to have its parts broken or to need frequent repairing.

I am'aware that the standard, the bar D, the bifurcated lever with its pedal, and the springs C are not new, and su eh I do not el ai m, broadly, as the said elements are shown in patents granted to me July 2l, ISS5,.and January 20, 188,5, numbered, respectively, 322,847 and 311,083.
